1977 XS650 tripmeter knob broken off

[nhsteve]

Well, actually, it's on an RD400. But the meters are roughly the same. A previous owner put clubman bars on the bike, and promptly cleaned the tripmeter knob completely off. I've read other threads indicating that a small screw (jeez- it must be small- I can't even see it on the '78 XS I have!!) holds the knob on, and the meter gasket looks like it has a hole to accommodate the shaft.

Is there a reliable speedometer repair outfit that one could send to, either for parts or service?

HVC Cycle has reset knobs and they are billet aluminum ! I was looking at these, thinking they might work on our XS650’s .
Of course you would need to verify the fit for yourself , but it might be an option.

The parts diagram indicates the same knob is used on the RD400 and the 650, and it's still available from Yamaha. There's no screw for it as far as I know. The knob itself is threaded inside, as is the shaft it screws onto.

Thank you both. As the meters for the RD250/350 are more like the ones from the '74/'75 TX/XS650s, they may not quite be right for the RD400 I have. But I had forgotten about HVC (odd, as I use them a lot), so thanks for the reminder.
I'll try to make some time this fall to get the RD speedo out of the cup so I can investigate. My fear is that the shaft that the knob threads on to has been snapped off. In which case I'll be in search mode for either a dead-but-intact similar meter I can steal the part from, or an expert who can make the repair (preferable- hmmm....... maybe HVC?)

Thanks again!
